' No. 10,444., datednay 20,1895, anein Hungary, No. 4,009, dated October 26, 1895,) of which the following is a specification.

This invention has reference to an improved petroleum motor of that class which are known as single-stroke motors, in which every stroke of the piston is a power stroke, while the well-known petroleum-motors are usually arranged on the so called fourstroke principle. obtained by arranging alongside of the working cylinder a supply-cylinder, the piston of which alternately sucks in petroleum-vapors and forces the same into the working cylinder, which suction and supply are regulated by means of suction and intermediate supply valves, the latter being actuated by connectin g-rods from eccentrics on the driving-shaft, so as to produce the proper communication between the working and supply cylinders. The suction-valves of the motor are connected with suitable petroleum-vaporizers in which dry vapors are produced, so that nopgummy or other sediments are produced in the working cylinder.

The invention consists of a petroleum-motor comprising a working cylinder, a supplycylinder for the working cylinder, dischargevalves for the working cylinder, suction and intermediate supply valves for the supplycylinder, connecting-channels between the working cylinder and the intermediate supply-valves of the supply-cylinder, pistons in said cylinders, the piston in the supply-cylinder being arranged and adapted toY move somewhat in advance of that in the working cylinder, eccentrics on the driving crankshaft, and connecting-rods between the eccentrics on the driving-shaft and the discharge The single-stroke effect is and intermediate supply valves, respectively, so as to produce the regular supply of vapors for the compression and combustion of the same, and also to produce the discharge of the heated gases which are conducted to the vaporizers that are arranged in connection with the suction and discharge valves, as will be fully described hereinafter, and iinally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved petroleum-motor. Fig. 2 is a plan view of the same, parts being shown in horizontal section through the working and supply cylinders. Fig. 3 is an end elevation showing one of the vaporizers and its connections with the cylinders in dotted lines. Figs. 4 and 5 are respectively a vertical longitudinal section and an end elevation, with the cover removed, of the vaporizer. Fig. 6 is an end elevation of the inner cone of the vaporizingchamber, with the outer casing, to which it is attached, in section; and. Fig. 7 is a longitudinal 4section of the inner cone.

Similar letters of reference indicate corresponding parts.

My improved motor consists of a working cylinder a and a vapor-supply cylinder b, in which are arranged pistons c and d, respectively, the piston-rods of which are so connected with the driving crank-shaft D that the piston d of the supply-cylinder is moved slightly ahead of the piston c of the working cylinder, as shown in Fig. 2. The working cylinder a is provided with two dischargevalves h' 71.2, which are actuated by a connecting-rod h, that is operated from the eccentric h3 on the driving-shaft. The supply-cylinder l) is provided with four valves, namely, two intermediate supply-valves c c2 and two suction-valves d cl2. The intermediate supply-valves c c2 are actuated by a connectingrod c3, which is operated by an eccentricc4 on the driving-shaft D.. The suction-valves d' d2 are connected with the petroleum-vaporizers, to be hereinafter described, so that the piston cl sucks in the vapors during the forward-and-backward stroke of the same, and the intermediate supply-valves c c2 are connected by pipes or channels r, on which are arranged the supports fof the igniter, with the working-cylinder a, Simultaneous operation of the outlet-valves h h2 is produced by the connecting-rod h by means of two pivoted actuating arms or levers H3714, which engage the lower ends of the spindles of the valves and which are in turn engaged by the lateral projections h5 7L of the connecting-rod h, so that when one of the valves 7i 71,2 is open the other is closed, and vice versa. The actuation of the intermediate supplyvalves c c2 is produced by angularprojections on the connecting-rod c3 in similar manner.

My improved petroleum-motor is operated as follows: The piston in the supply-cylinder serves for sucking in the vapors into one end of the cylinder and for supplying the vapors, at the other end, simultaneously to the Working cylinder. When the piston d moves in forward direction, the suction action of the same closes the intermediate supply-valve c and opens the suction-valve d. At the same time, the Working cylinder d is charged with vapors by the opening of the intermediate supply-valve c2, while the suction-valve cl2 is closed. The intermediate supply-valve c2 is not opened by the connecting-rod c3 until the products of combustion are forced by the piston c of the working cylinder a, through the outlet-valve h2, and the latter is closed again, so that the piston c is in the position shown in Fig. 2. In this position of the piston c, the supply of vapors from the supply-cylinder b takes place, the piston CZ of the supplycylinder forcing the compressed vapors from the supply-cylinder into the working cylinder. The intermediate supply-valve c2 is then closed, so that by the continued forward motion oi' the piston c the already compressed petroleum-vapors are still more compressed in the working cylinder. lVhen the vapors are compressed to the highest point of compression, the outlet-valve h2 and the intermediate supply-valve c2 are closed and the ignition takes place.

The ignition can be accomplished in any approved manner, preferably by electrical nieans. The explosion of the vapors forces the Working piston c in backward direction, so that the same successive operations can take place at the opposite side oi' the piston, namely, the discharge of the products of cornbustion filling the working cylinder with a new charge of vapors from the supply-cylinder, and the compression of these vapors at the opposite end of the Working cylinder causing the ignition of the compressed vapors, so that the return stroke of the piston takes place, and so on.

Both cylinders as well as the valves. are cooled in any approved manner by means of water which is supplied into a jacket .l of the working cylinder,then conducted into a jacket J of the supply-cylinder, from which it is conducted off in any suitable manner. The

piston and piston-rods may likewise be cooled in any well-known manner, and a suitable safety-valve has to be provided on the supply-cylinder, so that in case of a premature ignition of the gas the bursting of the cylinder is prevented.

The construction of the petroleum-vaporizer is shown in Figs. 4 to 7. The vaporizcrs are constructed with a view so as to produce perfectly dry vapors, which, after combustion, do not leave any sediment in the Working cylinder. For this purpose they are arranged on the motor and connected with the discharge-valves h h2 and the suction-valves d' d2. The vaporizer consists of an exterior casing m, which is provided at its larger end with a cover m and at its smaller end with a screw-coupling x, and in the cover with a like coupling y.

In the exterior casing. is arranged a vaporizing-chamber which is formed by two concentric cones n o, the inner cone 0 being provided with exterior circular flanges o', fitted to the inner surface of the outer concentric cone n. The space between the flanges is filled with iron filings. The petroleum is supplied by means of a suitable pipe i and passes successively through the channels formed between the flanges oin the direction of the arrow shown in Fig. l. The vapors are discharged in perfectly-dry condition through the pipe g, which is connected with one of the suction-valves of the supply-cylinder. The products of combustion are conducted from the discharge-valves through the coupling w of the vaporizer and pass around between the same and the exterior cone n, so as to vaporize the petroleum in passing through said cone. The products of combustion pass olf through the coupling y. Two of these Vaporizers are arranged one in connection with each suction-valve of the supply-cylinder.

It is obvious that before starting the motor the vaporizer should be heated up by means of a lamp or other suitable heating device until the hot products of combustion are supplied from the discharge-valves to the in going ends of the vaporzers, so that they can heat up the petroleum and produce the vaporization of the same.

Iflaving thus described iny invention, I claim as new and desire to secure by Letters Patentl. In a petroleum-motor,the combination of a working cylinder provided with dischargevalves, a supply-cylinder arranged alongside of the working cylinder and provided with suction-valves and with intermediate supply-valves, pistons in said cylinders, the piston in the supply-cylinder being arranged and adapted to move somewhat in advance of that in the Working cylinder, a vaporizer, pipe connections between the vaporizer and the suction and discharge valves, and means for actuating the suction, intermediate supply and discharge valves in such a manner that after tlie charge of vapors in the working cylinder is compressed the ignition and IOO IIO
